I develop commercial Ruby On Rails applications for the last 3+ years and enjoy it a lot. Most of my projects start from a point where a customer has a problem and doesn't know how to solve it. I help small businesses to map there business processes, design a suitable solution and implement it. Sometimes it involves mobile client applications, external APIs, third party software integrations — anything that solves a business problem the best way. Meanwhile, I am a co-founder and a CTO in a German startup myCleaner - https://www.mycleaner.com. I have implemented the entire web solution a of myCleaner alone and you can take it as a reference of my latest work. I'm looking forward to give your business a boost with a RoR web app.
